The big companies are the private industry. But they're faced with a short-term need to show a profit in short-term.

Sending a couple of guys to the Moon and bringing them back safely? That's a stunt! That's not historic.

The beauty of Hawaii probably surpasses other places. I like the Big Island and the two mountains, Mauna Loa and Mauna Kea, where you can look out at the stars.

The pilgrims on the Mayflower landed at Plymouth Rock. To my knowledge, they didn't wait around for a return trip to Europe. You settle some place with a purpose. If you don't want to do that, stay home. You avoid an awful lot of risks by not venturing outward.

Let's not spend resources that we don't need to be sending astronauts back to the moon. Let's not spend expensive resources on bringing people who have reached Mars back again. Prepare them to become a growing colony.

There should be an international lunar base. That is certainly doable.

I'm not in favor of just taking short-term isolated situations and depleting our resources to keep our climate just the way it is today.
